This new underwater viewer eliminates bright sunlight, waves, and suspended solids from complicating below water surface viewing. Lightweight and crush-resistant, this amazing ecological tool can also be used to view Secchi disk readings. The 26 long tube with polycarbonate bottom has no surface glare or internal reflection, thus eliminating errors. Its black interior, flotation collar, neoprene viewing mask and handle make for consistent readings, despite the variety of your surroundings. Instructions included. Grades 6-12.
